The EV Group 520 HE Wafer is a wafer bonder for packaging and bonding applications. The EV Group 520 HE Wafer is manufactured by EV Group (EVG).[1]
What it is
Where it fits in the process flow
General reference — not yet source-verifiedThe 520 HE wafer bonder is used in the packaging and bonding segment of semiconductor manufacturing, after wafer fabrication and before final assembly and test. In the process flow, the bonder typically receives singulated or unsingulated wafers from front-end processing and joins them to form stacked structures. Downstream processes may include thinning, dicing, and further interconnect formation.
